Cushion for a chair, especially a detachable cushion for a child&#39;s seat

ABSTRACT

The present invention relates to a cushion for a chair (1), especially a demountable cushion (2) for a chair for children, and for the object of providing a cushion which simply and effectively can be mounted on a child&#39;s chair and correspondingly in a rapid and effective manner can be demounted therefrom, it is according to the invention suggested that the main shape (3) of the cushion comprises a main portion (4) serving to support the back portion of the user, and one or more side portions (5a, 5b) serving as extended support portion and/or affixing portion.

FIELD OF THE INVENTION

The present invention relates to a cushion for a chair, especially adetachable cushion for a chair for children, comprising a main portionwhich substantially covers the user's back support.

BACKGROUND OF THE ART

From NO 132.782 (Peter Opsvik) there is known a chair for childrencomprising to side members which at the bottom merge into a leg supportand at the top carry a back rest connecting the upper portions of theside members. At the inner surfaces of the side members there areprovided tracks, wherein can be inserted the side edges of a seat plateand a foot plate, respectively, which plates thereby are given anoptional height and thereby the possibility of being used by both smallchildren, larger children and adult persons for one and same chairstructure.

In connection with such chairs for children which usually aremanufactured from wood or another suitable material, there has been arequirement for a back cushion and a seat cushion which in a simplemanner can be attached to and detached from the back support and seat,respectively, for thereby improving the sitting comfort of the chairuser.

U.S. Pat. No. 4,235,474 relates to a chair cushion for retaining a babyin a chair, but here the cushion is provided with an upper pocket whichis to be threaded onto the back support. Consequently, this cushion doesnot comprise a specifically designed main portion rendering support forthe back portion of the user, at the same time as the back portioncomprises one or more side-portions combining the attachment of thecushion itself as well as additional support for the user, especially inconnection with chairs for children both with and without a guard.

U.S. Pat. No. 4,824,320 relates to a cushion with assembled back portionand seat portion, but without slit side portions which in connectionwith for example chairs for children of the type "tripp-trapp" asdiscussed in said NO 132,782 can pave the way for additional upholsterywhether such chairs are used with or without a sitting guard.

U.S. Pat. No. 5,005,903 relates to a child's auto seat, wherein issuggested an upholstery around the child's seat, such that a passengersplaced next to the child's seat shall not be injured. Neither has thispublication any relevance in relations to the present child's cushion.

U.S. Pat. No. 5,042,878 relates to an invalid chair cushion having sideportions which do not form a part of the back portion, but a part of theseat front. It is true that there are suggested some very narrowattachment straps on the back portion, but these are only intended asmeans for attaching the cushion to the chair, see especially FIG. 3 inthis publication. Otherwise, the discussed side portions constituting apart of the seat front are adapted to extend all around the chair back,which most apparently is seen in FIG. 2 of said publication. Said priorart side portions will thus constitute a separate part of the cushionsmain portion itself, and said prior art side portions can not on the onehand be used as means for attachment to the chair with expandedsupporting portion, and/or attachment means on a supporting guard, atthe same time as the expanded supporting function is conserved.

BACKGROUND OF THE INVENTION

An object of the present invention is to provide a cushion for a chair,especially a detachable cushion for a child's chair which in a rapid andsimple manner can be mounted on a child's chair and also in a rapid andeffective manner can be demounted from the chair in connection withcleaning.

A further object of the present invention is to provide a cushion for achild's chair which can be used not only for chairs for children withouta child's guard, but which also can be used for the same chair when sucha supporting guard is mounted thereon.

Another object of the present invention is to provide a cushion whichcan be manufactured in a simple and noncostly manner, at the same timeas the material is utilized in an optimum way.

Still another object of the present invention is to provide a cushionfor a child's chair giving the possibility for additional upholsteringat optional portions without reducing the requirements for simple andrapid mounting and cleaning requirements.

SUMMARY OF THE INVENTION

These and other objects of the present invention are achieved by acushion of the type as stated in the introductory part, which accordingto the invention is characterized in that the main shape of the cushionin addition to the main portion serving to support the back portion ofthe user also comprises one or more side portions serving as an extendedsupporting portion and affixing portion on chair back and/or child'sguard.

Further features and characteristics of the present invention willappear from the following description taken in connection with theappended Figures, as well as from the appending patent claims.

DISCLOSURE OF EMBODIMENTS

In FIGS. 1-6 there is in connection with a chair, here designated byreference numeral 1, especially a child's chair, illustrated a firstembodiment of a demountable cushion 2 according to the presentinvention. The cushion 2 itself has a main shape 3 comprising a mainportion 4 serving to support the back portion of the user, said cushion2 also comprising one or more side portions, appropriately two sideportions 5a and 5b, respectively, serving as an extended supportingportion and/or affixing portion.

In the embodiment illustrated in FIGS. 1 and 2, i.e. without any mountedguard, the side portions 5a and 5b, respectively, are provided asbendable portions 6a, 6b adapted to be affixed around a portion 7 of aback support 8a, 8b, and in the illustrated chair 1 the back support iscomposed of two parallel ribs 8a, 8b, extending substantiallyhorizontally in a spaced relation. The side portions 5a, 5b of thecushion can then be adapted to be attached at the lower back support rib8b of the chair 1 and will then serve to expand the back support portionin the area of this back support rib 8b.

Alternatively, as illustrated in FIGS. 3 and 4 wherein the chair 1 is ofthe same type as illustrated in FIGS. 1 and 2, but wherein a child'sguard 10 has been attached to the chair 1, the side portions 6a, 6b ofthe cushion 2 are appropriately affixed around appropriate portions 9a,9b of said child's guard 10.

From FIGS. 5 and 6 it appears that the cushion 2 prior to mounting has asubstantially rectangular shape, and that the main portion 4 whichsubstantially serve to support the back area of the user also has asubstantially rectangular shape, said side portions 5a, 5b beingprovided by means of appropriate notches 12a, 12b.

These notches 12a, 12b can be arranged substantially parallel inrelation to each other and from the one side edge 3a of the main shape3. However, it is to be understood that other shapes and proportionsbetween the various portions of the cushion can be used within the scopeof the present invention.

The side portions 5a, 5b are appropriately provided with affixing means13a, 13b provided on the outer portions of the respective side portions,which affixing means can co-operate with corresponding affixing means14a, 14b on opposite edge portions of the main portion 4 of the cushion,see also FIG. 4. Such affixing means can for example comprise velcrolocks, straps, or similar, providing for an affixing objective forsimple and reliable mounting of the cushion on the child's chair inquestion.

The cushion 2 also comprises further affixing means 15a, 15b provided onthe mounting side 4a of the main portion 4. These further affixing meanscontribute, together with the previously discussed affixing means, to amounting of the back cushion in an easy and safe manner, especiallywithout the latter sliding around or being displaced in an uncomfortablemanner for the user, see also FIG. 2.

In the embodiment illustrated according to FIGS. 1-6 the cushion 2 iscontemplated to be formed as a separate unit, and it is appropriate thatthis separate unit is related to a separate seat cushion 20, for exampleof the embodiment as illustrated in FIGS. 7-9. There is here illustrateda separate seat cushion 20 which is adapted to the seat 21 of thepreviously discussed chair 1, whether this is provided with or withoutsaid child's guard.

The separate seat cushion 20 is provided with excess edge portions 22a,22b, 22c which can be slipped around corresponding edge portions of thechair seat 21 for the attachment thereto, and if these edge portions22a, 22b, 22c are arranged for being turned inside out, which isindicated by the arrows in FIG. 9, this will allow that an arbitraryside 24a, 24b of the seat cushion can constitute the use surface.

Appropriately, the seat cushion 20 can be provided with a front cut-out25, which is specifically favourable if the cushion 20 is to be used ona chair seat 21 which is arranged to give support for a child's guard10, see especially FIG. 3, said cut-out 25 allowing the mounting anddemounting of said cushion 20 without removal of the child's guard 10.

It is also appropriate that the seat cushion 20 has a main surfaceextension corresponding to the surface extension of the seat 21, whichrenders the same good cushion function independent of the seat depth andthe height adjustment of the seat 21.

It is to be understood that both types of cushions can be manufacturedseparately, but it is also contemplated a certain form of associationbetween said cushions, for example by means of appropriate detachableconnections.

Further, it is to be understood that the separate or connected cushionsmay favourably be manufactured from a material which can easily becleaned, and said cushions should also in a rapid and effective way bedemounted and remounted in relation to the chair, and said cushion orcushions should also have an appropriate user softness.
